Cleaning nozzle



Jan. 10, 1939. H. F. BEEMAN CLEANING NOZZLE Filed March 5, 1936 PatentedJan. l0, 1939 UNITED STATES PATENT oI-Flcs- Schirm.

This invention relates to a` nozzle designed for use in connection withan air pressure hose or the like. l

An object of the invention is to Aprovide a nozzle which can be coupledreadily to various types of couplings or chucks on airflines such asfound in automobile service stations, it being posl nozzle that it canbe adjusted angulariy relative to its vaived hose connection, wherebythe structure can be arranged most advantageously for use either as asuction cleaner or a blower.

A still further object is to provide a quickly adjustable clevis of newand novel construction for securing a hose to the device.

With the foregoing and other objects in -vi'ew which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully -describedand pointed out in the claims, it being lunderstood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

In the` accompanying drawing the preferred formof the invention has beenshown.

In said drawing- Figure 1 is a central longitudinal section through thecomplete device arranged for use as a suction cleaner, an air line beingshown connected thereto.

Figure 2 is a section on line 2-2, Figure 1.

Figure 3 is a side elevation showing the nozzleA adjusted for use as ablower.

Referring to the figures by characters of reference, I designates thetubular body of the nozzle preferably tapered toward one end as shownwhile its other end has a head 2 inclined relative to the body andhaving air inlet 3 which can be of any desired proportions butpreferably is in the nature of a narrow transversely extending slot suchas lcommonly employed in the suction heads of vacuum cleaners.

The center of the head is thickened as at 4 and has a fiat top 5. A bore6 extends from the top 5 down into the thickened portion 4 and has v. anoutlet 'I 'at ,its lower end which is in line with the axial center ofbody I and opens thereinto. The upper portion of the bore is engaged bya threaded pivot bolt 8. An annular groove 9 is formed in the boltbetween top 5 and the head I0 oi!A the-bolt and opening into this grooveis a diametrical passage I I which opens into the upper end of alongitudinal .passage I2 in .the bolt.

This passage communicates with the space be' neath the bolt.

A sleeve I3 is rotatably mounted on the bolt 8 between top 5 and headand gaskets I5 are interposed' between the ends-of this sleeve and thetop and'head to insure tight connections. A radial extension I5 isformed on the sleeve and has an opening I'I in communication with thegroove 9. In this opening I1 is seated a screw-thread- Aed nipple I8projecting from one end of a valve casing I9. A valve chamber is formedin the casing and a. passage 2| extends therefrom through nipple I9.

A threaded socket 22 is formed in the other end of the valve casing andcommunicates at 23 with the bottom portion of chamber 29 at a point outof line with passage 2|.

- A slide or plunger valve 24 is mounted in chamber 20 and is yleldinglysupported by a spring 25. This valve has an exposed head 26 to bedepressed by hand and the valve normally closes communication betweensocket 22 and passage 2I. When it is depressed, however, it establishesthis communication.

Seated in socket 22 is a nipple 21 at one end of a coupling member 29having a. trough-like extension'29 at its other end. An upwardlyinclined stud 30 is formed in the inner end portion of the extension 29and opening therethrough is the inclined end of a passage 3l whichextends through thenipple 21 to the vsocket 22.

The member 28'is straddled by a yoke 32 pivotally connected thereto at33 and carrying a set screw 34.

When it is desired touse this device the coupling head H of an air lineor hose L is placed in the extension 29 and on the stud 3l) and the yoke32 is swung into position therearound. By then tightening screw 34 thehead H will be clamped tightly in place.

If the nozzle is to be used for suction purposes the parts are arrangedas shown in Figure v1 and a tube T is tted on the tapered body landextended to a bag or to any point where they removed dust and dirt areto be discharged. Valve 24 is depressed to establish communicationbetween passages 3I and 2| and 'air under pressm'e is immediatelydelivered to passage I2 from which it will `escape in a strong jetthrough outlet I and axially within body I. 'I'he force of this jet willcause a suction into the body through inlet 3 so that dust and dirtadjacent to the ful in cleaning the interior of a vehicle body, thevengine of an automobile, and for other cleaning purposes. It isadvantageous because of its simple and inexpensive construction and theease with which it can be handled. The coupling means employed allowsthe nozzle to be coupled to the heads of. various types of air lines.

What is claimed is:

1. A cleaning nozzle including a handle, means at one end thereof forattaching it to an air line, there being a passage extending through thehandle, a valve in the handle for controlling the ow of air through theLpassage, a tubular body.

having a suction head at one end and a discharge outlet at its otherend, there being an air outlet duct in the body adjacent to the suctionhead and coaxial with and directed toward the discharge outlet, and apivotal connection between the other end portion of the handle and oneend portion of the tubular body, said connection establishing andmaintaining communication between the passage in the handle and the airoutlet, said body and connection being rotatable relative to the handle.

2. A cleaning nozzle including a tubular body having a suction head, adischarge outlet, and

an air outlet duct in the head coaxial with the body and dischargeoutlet and directed toward said outlet, a handle having a passagetherein, means for pivotally connecting. the handle to the body forangular adjustment relative thereto,

said means maintaining communication between, the passage and the airoutlet duct vat all times during the adjustment of the handle and body,and a valve in the handle for controlling the flow of air through thepassage to the connection and air outlet.

3. A cleaning nozzle including a tubular member, means at one endthereof for attaching it to an air line, 'there being a passageextending through the tubular member, a valve in the tubular member forcontrolling the ow of air through the passage, a tubular body having asuction head at one end and a. discharge outlet at its other end, therebeing an air outlet duct in the body adjacent to the suction head andcoaxial with and directed toward the discharge outlet, and a pivotalconnection between the other end portion of the tubular member and oneend portionof the tubular body, said connection establishing andmaintaining communication between the passage in the tubular member andthe air outlet, said body and connection being rotatable relative to thetubular member.
